OT: I had to register as a new user just so I could answer this. It thinks my geophi user has attempted to login too many times (huh?), so makes me enter a "captcha" code. Entering it correctly, it tells me it was entered incorrectly. Tried this numerous times with different captcha codes, it still thinks I am entering them wrong. I had this problem before, and somehow got around it but can't remember what I did.

Peter,You are obviously using Cressman for your analysis since that is the only method that allows you to "tune" the reduction setting. That is why I was asking for "Barnes" settings. Thanks for the information.

The Barnes method does not allow you to change the "Reduction", that is ONLY for Cressman and is greyed out the rest of the time. From the DA Manual (page 89): "Reduction - Determines a reduction value used in the Cressman analysis method for upper air data."

Going back and checking the Analysis tab under prefences shows the following:

Analysis type:Nearest Neighbor - Only the Smoothing Coefficient and Smoothing passes can be edited; all others greyed out, INCLUDING Automatic Smoothing.Weighted - Gamma and Reduction are greyed out; all others can be edited. IF "Automatic smoothing" is checked, THEN Surface radius, Upper radius, Gamma and Reduction are greyed out and can not be edited.Barnes - Only Reduction is greyed out; all others can be edited. IF "Automatic smoothing" is checked, THEN Surface radius, Upper radius and Reduction are greyed out and can not be edited.Cressman - Only Gamma is greyed out; all others can be edited. IF "Automatic smoothing" is checked, THEN Surface radius, Upper radius and Gamma are greyed out and can not be edited.

However, there is a problem when trying to use this grouping for upper air isoplething. It looks terrible until 'Automatic Smoothing' is rechecked, then it looks excellent for that too. Not sure what the issue is, perhaps the upper radius slider doesn't go high enough? Anyway, this causes problems when running automated scripts like I do. The two don't want to cooperate with the same settings. I'm hoping Tim will add a toggle for AS'ing that can be inserted into scripts.
